Re: [PHP] yesterday's day of week

[Justin French]

There is a magic little function called strtotime()... it takes just about
any english phrase, and acts on it... there are examples in the manual:

http://www.php.net/manual/en/function.strtotime.php

In this case, I'm guessing you'd want

$yesterday = strtotime('yesterday');


Another approach would be to get the current time stamp (or any time stamp),
and minus 24 hours from it:

60 seconds * 60 minutes * 24 hours = 86400 seconds.

$yesterday = time() - 86400;


Either way, you've got a timestamp (seconds since some date in 1970)
representing yesterday, which you can feed into date():

echo date('l',$yesterday);
echo date('d',$yesterday);
echo date('D',$yesterday);

etc etc

You're trying to subtract 1 from a string.

I'm flabbergasted -- where did you look?

The proper way of doing this (ie getting yesterday's day of week and not 
subtracting 1 from a string) is to look at the examples in manual.
